摘要
采用低温燃烧法分别制备了Y2O3:Eu^3+和钐(Sm^3+)、铈(Ce^3+)掺杂的Y2O3:Eu^3+红色荧光粉,并研究了反应温度及掺杂量对荧光粉性能的影响.使用激光粒度仪、X射线粉末衍射仪和荧光光谱仪,对样品的物相、粒度及发光特性进行了表征和分析.结果表明,Y2O3:Eu^3+的最佳反应温度为200℃,Sm^3+和Ce^3+掺杂Y2O3:Eu^3+的粒径分别分布在396~615 nm和531~955 nm,Sm^3+和Ce^3+的掺杂均能显著增强Y2O3:Eu^3+红色荧光粉的发光性能.
In this work,Y2O3:Eu^3+,Sm^3+and Ce^3+doped Y2O3:Eu^3+phosphors was synthesized by low temperature combustion method,respectively,and the effect of different reaction temperature and doping content on the performance of Y2O3:Eu^3+phosphors was investigated.The phase,particle size and luminescent properties of samples were characterized and analyzed by x-ray diffraction,laser granulometer and fluorescence spectrometer.The results indicated that the optimal reaction temperature of Y2O3:Eu^3+was 200℃,the particle size distributions of Ce^3+and Sm^3+doped Y2O3:Eu^3+were about 396~615 nm and 531~955 nm,respectively,and the Sm^3+or Ce^3+doped Y2O3:Eu^3+could significantly enhance its luminescence performance.
